Manga
Hakufu's widowed, extremely promiscuous and flirtatious mother, a strong fighter, and a loving yet strict mother who is not above getting drunk at parties with her daughter or pummeling her into the floorboards. She unexpectedly moves in with Koukin and Hakufu. While she teases Koukin for his crush on her daughter, she is against the idea of Koukin and Hakufu being in a romantic relationship. She accepts Hakufu's fate and shows no resistance whenever her daughter faces her apparent doom. However, when she found out that Kakouton protected Hakufu from the Ugan gang, she becomes more optimistic about everyone's attempts to change their fates.

Anime
She is otherwise the same except that she is much stronger in the anime. She regularly punishes Hakufu, especially when Hakufu calls her an old hag. These punishments are usually spankings but can sometimes be something more violent. In one scene, she throws Hakufu through a door. Despite being inactive, she is still a very skillful fighter. She was able to defeat Toutoutsu and his Ugan gang after they attack Koukin and Hakufu outside their home. She is attracted to Kakouton and flirts with him whenever they meet, leading Kakouton's friends to think they are in a relationship. Also, she seems to approve of Koukin's crush on Hakufu more; in the first series, she once took Koukin's pillow, then put it in Hakufu's bed and encourages him to sleep next to Hakufu much to his embarrassment.
